Problems with a 2.7 L turbo

Crafty 88 · February 20, 2022

Hi everyone been a while since I posted been a members in the 90s but had to make a new profile anyway I’m having issues with my 2019 2.7 L turbo I have 20,000 miles on it the issue is when it’s below zero outside and you started in the mornings it goes into limp mode I’ve had it in the dealer several times they replace cam sensors cam actuators they even took the wiring harness out and inspected it apparently I’m the only one at this time that’s having this issue and they been working closely with the GM engineers now other people are starting to have problems got a phone call from my local dealership last week saying now that GM wants my motor so they’re gonna replace my motor with a new one and GM wants my motor to do some tests on it they’re going to stick it in the big freezer hook it up to some monitors and find out what the issue is and then when they figure it out they’re gonna put a service bulletin out my question is has anybody else had this problem needless to say when talking to my salesman I am going to be ordering a 3 L diesel here so in two weeks the truck goes in for a new motor we will see what happens thanks

You can just swap the gas motor with a diesel?

No they’re going to put a brand new 2.7 L in what I meant is I’m ordering a new diesel pick up because I am not keeping this one since GM won’t buy it back

Oh ok, lol. I didn't care for the 2.7l when I test drove one. I got the 5.3, and it has been rock solid this far.

That's B S.

Tell them they can have the motor if they give you a new truck. Even trade.

Would be a lot more than just an engine swap.

3.0 is always mated to the 10 speed,

2.7 is never mated to the the 10 speed.

Would also require adding a def tank and fill system.

Emissions and exhaust are different.

Likely different radiator/cooling system.

etc

I was wondering if the replacement 2.7L would be the newer high output one....

Pretty sure that's not how warranty works...

GM would have hundreds of thousands of vehicles bought back if warranty worked that way lol

Lets see here, $1 billion dollars in used dead trucks or $100 million in warranty work for engines/transmission. Doesn't take a genius to figure out what option they are going to take.

Keep us up to date on this! I don't have problems in mine, just surpassed 30k miles.

Agreed. 2.7l was boring. Nothing replaces v8's, and if you think otherwise, stop smoking that weed and start realizing its real life

Does the 2.7T have active grill shutters? If not, I wonder if the dealer or GM even thought about the intercooler freezing up, since the OP mentioned it happens below O degrees F. This has been a problem in the 1.5T found in the newer Equinox/Terrain lineup. The solution there was in some cases an intercooler replacement but in most cases GM just provided those in cold climes a radiator cover to be used during cold weather.

Yes. It has active grill shutters.

I'm thinking about buying the 2019 2.7 leader turbocharged to tow a 2465 Lance almost 30 ft trailer that's only 7 to 8,000 lb when full. Will that be a problem? And I didn't quite understand if you had a gasoline or diesel engine. Diesel is known to be thick in cold conditions. But it sounds like you have a gas so, luckily I live in Texas and we probably won't travel anywhere below zero.
